I've been gone a long time, and have just begin poking around now.
I'm guessing that you killed it during the fall purge. It did of course have limited traffic, but I certainly used it all of them time when I was not posting. The most useful topic was the new agent announcements with Crew's remark that new agents frequently were hungry for new clients.
I can see that an update feature is now on AgentQuery.com with an email address, but to spot a new agent there would be a matter of luck after one had performed a search.
Ah well. There are always agency websites.... at least most of the time.
